Abstract

The paper presents the design of a virtual private network able to support mobility of the user. The VPN has two parts: the access network and the public Internet to connect to the corporate intranet. The access network can be based on GPRS or a WLAN. The system uses the security provided by the access network and IPSec in the public Internet. The mobility of the terminal is supported by the use of Mobile IP that allows maintaining the intranet private IP address when roaming. As mobile VPN is offered as a service, the provisioning is considered an important part of the system. Scalability guides the design and implementation phase to assure a smooth increase of the size in the number of VPNs and users.
